Sun Tzus The Art of War Essay -- Sun Tzu Art War Essays
Sun Tzu's The Art of War à à à à à The translation of the ââ¬Å"Sun Tzu: The Art of Warâ⬠ancient Chinese text has been given by many different writers. Samuel B. Griffith, Brigadier General, retired, U.S. Marine Corps; is a proven strategist that studied the English commandoes war fighting skills as a Captain. As a Major, Griffith was hand picked to serve as Executive Officer under the command of Lieutenant Colonel Merritt Edson of the 1st Raider Battalion, one of the battalions that perfected the amphibious landings during World War II. Samuel B. Griffith gives his in-depth study on ââ¬Å"Sun Tzu: The Art of Warâ⬠and how Mao Tse-tung used the strategies and teachings of Sun Tzu while commanding the Red Army of China. Griffithââ¬â¢s translation of Sun Tzuââ¬â¢s work is written in three parts: Introduction, Translation, and Appendix. PART 1: INTRODUCTION à à à à à In his first chapter of his study titled The Author, Griffith gives many different possibilities as to who the actual author of the writings is. Griffith sites many theories from other sources trying to validate the origin of the author, but settles on one basic theory for the text. The Art of War was written by a single author probably around the time of the Warring States and during the periods from 400-320 B.C. (p. 11) Furthermore, Griffith states that there is not enough evidence to positively say if a person named Sun Tzu actually wrote the book or if it was written as a tribute to him, and the case of the authorship remains unsettled. à à à à à The second chapter, The Text, of Griffithââ¬â¢s study focuses on the text itself. There has been debate about how many chapters were originally in ââ¬Å"The Art of Warâ⬠: Eighty-Two or Thirteen. (p. 13) Griffith gives a sound theory that the current thirteen chapters were the only writings. Based on copywriting errors, the eighty-two chapters were probably written into thirteen categories (or chapters) while trying to transcribe written work onto paper from silk or wood. Griffith also asserts that the text was used for entry-level war fighting studies in early Chinese military academies. à à à à à The Warring States is the subject and title of Griffithââ¬â¢s third chapter, which gives an enlightening look at the life and times in China after the defeat of the rule of Chin at Ching Yang in 453. (p. 20) The country was divided into eight individual warring sects (with the exception of Yen... ...g for you. An expendable agent is given false information on purpose. And a living agent is one that returns to the commander with information. PART III: Appendix à à à à à Griffithââ¬â¢s study also includes four different appendixes. The first is A Note from Wu Chââ¬â¢I, the second is titled Sun Tzuââ¬â¢s Influence on Japanese Military Thought, the third is Sun Tzu in Western Languages, and the fourth appendix is Brief Biographies of the Commentators. à à à à à Samuel B. Griffithââ¬â¢s translation of ââ¬Å"Sun Tzu: The Art of Warâ⬠is an inside look at military practices of today. I did not find one technique that is not or would not be utilized in modern military maneuver, leadership, or training. The most astounding fact is that the Art of War was written well over two thousand years ago, even at the most conservative date. Although most of the techniques in this text are already in practice today, the value of ââ¬Å"The Art of Warâ⬠is a never-ending treasure chest of knowledge, and it deserves a place as a required reading for anyone seeking knowledge about war fighting or the history of war.

ââ¬ÅEverymanââ¬Â and ââ¬ÅDoctor Faustusââ¬Â Essay
Both Everyman and Doctor Faustus are plays. They are written within different time Periods, with Everyman written in the medieval era and Doctor Faustus written in the Renaissance. Everyman and Doctor Faustus are both Morality Plays, these are specifically plays that existed within the Medieval period. They were popular during this period as they were intended to instruct the audience in the Christian way and attitudes to life. The morality play is essentially an allegory written in dramatic form. In the fourteenth Century, morality plays were mainly based on the seven deadly sins as in Everyman with each character representing each sin. Everyman centers around allegory. It focuses on the allegorical representations of moral issues with the inclusion of figures that represent abstractions of the issues that are confronted. Doctor Faustus follows the general five-act structure of an Elizabethan Romantic Tragedy. However Christopher Marlowe used the structure of an older Medieval form of English Drama, the morality play as a model. Morality plays tended to show the moral struggle of mans soul and the conflict of good and evil. This is evident in the play of Doctor Faustus who is embroiled in a battle between the temptation of the devil and God. You could argue that Doctor Faustus is not classed as a morality play. Because in the tradition of a morality play God and the devil are external forces that affect the individual. However, in Doctor Faustus it is far more of an internal drama inside Faustusââ¬â¢ own mind. Both are entirely didactic in nature, they were made with the intent to educate their audience in one respect or another. There was a moral to each that conveyed similar messages. Therefore the term ââ¬Ëmorality playââ¬â¢ correctly defines each one. The medieval time period in which Everyman was written contained a society that revolved around religion (Ecclesiasticism) The fact that Everyman can get nowhere without turning to religion directly reflects on the attitudes of the middle ages. There is constant references to the beliefs and ideas of the Catholic Church such as confession, penitence and the Virgin Mary this suggests the catholic centered society in which the play existed. It concentrates on the qualities of the catholic religion that are important in the journey to heaven. Everyman is a symbol of the human condition and how it is understood by medieval Catholicism. Whereas in the sixteenth century in which Doctor Faustus was written, saw a shift of Christian ideals. No longer was there only the strict belief in God but also the equal belief in the existence of the devil and the ââ¬Å"work of the devil.â⬠The medieval world placed God at the centre of existence, leaving the individual and the natural world in second place. The emergence of the Renaissance is evident in Doctor Faustus by the clash between the church and the introduction of knowledge through science. The Reformation caused a dramatic change at that particular time, England had converted from predominantly catholic to a protestant country. This shift becomes apparent in Doctor Faustus in the scenes with the Pope. The Renaissance was also a time when the bubonic plague was at its peak of destruction. As a result the plague was a great concern of the theatre, audiences and writers. The plague was a large part of Marloweââ¬â¢s life and work. Marlowe refers to the plague regularly in Doctor Faustus with examples such as ââ¬Å"A Plague on her.â⬠Here Marlowe is using speci fic language to reflect certain aspect of the precise period, being Reformation. When considering the audience of each play, this can again create disagreement concerning the meaning of the term ââ¬Ëmorality play.ââ¬â¢ Morality plays, as I have mentioned like Everyman, primarily express aspects of moral doctrine to the audience. In the Play Everyman, the anonymous author may have been a priest or teacher who was explaining the Christian values to an uneducated society. It is written by and for people of catholic religion. This would fit accurately into the description as a ââ¬Ëmorality play.ââ¬â¢ However, some may argue that Doctor Faustus is more comically delivered as opposed to morally. Elizabethan audiences often viewed great tragedies such as this in a slightly humorous manner. Scenes such as the one with the Popeââ¬â¢s food and drink being stolen highlights this point. Also Marlowe includes numerous comical characters such as Wagner and Faustusââ¬â¢ servant. Therefore can we still group this together with the other morality plays such as Doctor Faustus? Contrary to this, it is clear that the audience of the play Doctor Faustus are not simply an audience of ââ¬ËCommoners or clowns,ââ¬â¢ they have to employ a certain level of intelligence and education to understand the symbolism and al legory present in the play. We can acknowledge the play of Doctor Faustus as one from the Elizabethan period as its verbs differ from modern day usage, with phrases such as ââ¬Å"What see you?â⬠and ââ¬Å"You look not well.â⬠Also Elizabethan playwrights wrote in blank verse or iambic pentameter, as its evident here. Marlowe uses various Christian phrases to summon the devil, who is providing the power. The most obvious reference to Christian language is shown through Faustusââ¬â¢ Latin Chant which is used to raise the devil. Marloweââ¬â¢s technique of hyperbole is demonstrated by his regular usage of blasphemy in the play. By using exaggeration like this, Marlowe is affecting the audienceââ¬â¢s perception of the character of Faustus. The language used gives the character heroic stature. Contrast to Doctor Faustus, The language in Everyman is solely based on religion. There is reference to the original sinner Adam and the seven deadly sins, this mainly focuses on the notions of Christianity. The language used in both Everyman and Doctor Faustus represents the conflict between power and Christianity. In conclusion, Marlowe borrows many of the conventions of a morality play especially with the inclusion of the good and bad angels. This symbolizes his divided will. This is mirrored in the play Everyman where there is an obvious spiritual crisis of an individual who must chose between good and evil. Both Everyman and Doctor Faustus effectively reflect the periods in which they were written. Faustus is the product of an era that was deeply torn, it stands in the threshold between two periods-The Renaissance and the Middle Ages. It includes the notions of Good and evil, sin and salvation, as did religious dramas of the medieval period such as Everyman. Although some may see this comparison as the rejection of the medieval due to further emphasis on the individual rather than God. After all, the opening scene of Doctor Faustus was praising science and magic in favour of God. So where do we draw the line? Everyman statically reflects the period of medieval whereas Doctor Faustus focuses on the actual change in that particular period of the Reformation. Therefore it is possible to see the alteration from one period to another.

She deci ded that she would leave and hitchhike her way on up to Colorado where she continued the same lifestyle. In the midst of the horrible, unethical lifestyle, she was informed that her grandfather had committed suicide in his garage. I can only speculate that she felt alone in the world and needed to fill that void. So as she was ââ¬Å"Hitchhiking across America, Wuornos arrived in Florida and was presented with a potentially life-changing piece of luck: she met wealthy yacht club president, 69-year old Lewis Fell, who fell in love with her, and they were married in 1976.

The Fundamental Objectives Of Modern Ethic Committees
Delivering medical care is a two way street. Families rely on the hospital physicians and the care team to understand their desire for their love ones to receive care that is not biased, or prejudiced in any way. On the other hand, hospitals have a desire for families to understand their guidelines, policies, and laws that guide their efforts in caring for patients. When physicians cannot reach an agreed upon resolution in care between all parties involved (patient/surrogate, caregiver, or clinician) the use of the ethical committee is efficient (University of Washington School of Medicine, 2013). The fundamental objectives of modern ethic committees are; to encourage rights of patients, promote shared decision-making between patients,â⬠¦show more contentâ⬠¦The Use of the Ethical Committee The use of the ethical committee is to ensure that the code of medical ethics is adhered to at all times by hospitals and the care team. According to George D. Pozgar, (2012), ethics is a p art of philosophy that looks to make known the nature, determinations, defense and the founding principles of moral rules and the systems they comprise (p. 368). There are four pillars to health care; maleficence, beneficence, justice, and autonomy. First, maleficence deals with the care giver not causing the patient harm. Secondly, beneficence deals with showing kindness, compassion, and doing well to help others. Thirdly, autonomy deals with a patient having the sole right to make decisions about his/her medical care. Finally, justice deals the facility being fair in their risks and management when dealing with patients. According to the Patient Self Determination Act of 1990, ethically, and legally a patient has the right to choose their course of medical care. This of course is interpreted as no matter what a family member would like to see as an outcome for the patient, nor what the doctor deems as right; it is the patientââ¬â¢s sole right to determine their fate. This means the patient is responsible for choosing how they desire to spend their last days, continue a course of treatment or discontinue it. All advance directives put in place by the patient are governed by the courts of law and statutory. Each hospital facility

Interventions Of Separation Anxiety Disorder - 1046 Words
Interventions of Separation Anxiety Separation anxiety disorder (SAD) is one of the most common anxiety disorders in preadolescent children and can cause serious distress in a childââ¬â¢s life. Having separation anxiety disorder in childhood can significantly increase the chances of internalizing problems and other anxiety disorders. Unfortunately, because separation anxiety is common in children it is hard to determine if the behaviors the children are displaying are atypical. Although there are various types of treatment options for SAD, parent-child interaction therapy (PCIT) can be extremely helpful particularly in the school system as teachers can adopt the same techniques using teacher-child interaction therapy (TCIT). Therefore, the child is not only receiving treatment at home, their treatment is consistent at school. PCIT has proved to be an efficient and popular treatment for SAD, which will be outlined and confirmed in this paper through analysis of PCIT and TCIT. Parent-Child Interaction Therapy PCIT focuses on the idea that improving the parent-child interaction will lead to improvements in child and familyââ¬â¢s functioning (Pincus, Eyberg, Choate, 2005) that have been impaired due to SAD. Parentââ¬â¢s responses to their childââ¬â¢s anxiety allows for the continuation of the disorder.

Childhood memory Essay Example For Students
Childhood memory Essay I have many exciting and eventful memories from my childhood. But one of the most vivid and close to my heart is the times I spend with my grandparents and cousins during the summer when I was a young. These memories will forever stay close to my heart as my grandparents have both since died. A granny is someone who is always there for you, even when it feels like the whole world is against you or when you are in trouble. They never shout and scream always listen and they will always love you like there own children, this is a love that is unconditional. From I was a child my parents worked long hours and my granny was always there to support them. The feelings of love and security I got when I was with my granny were incredible. I am going to tell you about some of the most memorable times from this period of my life. Wouldnt you give anything to be innocent and uncorrupted by societies views and stereotypes again? The innocence of being young is something we do not appreciate until you are faced with deadlines and responsibilities of growing up. These memories are of pure bliss and are taken from the only period in your life in which you are free. I grew up in portrush in a small house in Brooklyn place but as my grand parents got older we moved closer to them in fact just up the road. Every day my dad would go to work and leave me at my grannies on the way. There I would eat my breakfast and prepare to go to school with my two cousins. I would return after school to watch television and chill-out. I loved it there, so as you can guess when the summer came I was incredibly excited. The summer is every Childs euphoria two whole months of freedom, fun and of course if you live in portrush sun and sand, well maybe not so much sun as sand. On the warm summer July mornings I would walk down the road to my grandparents house and would be greeted by the smell of warm toast and the aroma of a cup of warm tea. After breakfast the television would be turned on and my granny would go out and do a couple of hours work for an old butcher who lived up the street. When the TV went on, the fighting commenced. Give it to me! we would all scream in desperation not to miss a minute of are favourite shows. The screaming would wake my irritable grandfather. My granddad was a lovely man but not the sort you would want to wake in the morning as he would venture downstairs to tell us of and then proceed to behave fecetiously. Waking him would also mean sacrificing the television not something any of us wanted to do. From we were young my younger cousin Louise andà I built up and especially close friendship we were always there for each other. Whereas my older cousin and me would always fight, this usually ending up with me smacking him in the face and starting what seemed like world war three to us. This ultimately would end in one of use getting hit with a flying marble or getting stabbed with a pen. This rioting would ultimately end up in a rush to the kitchen to tell our wonderfully exaggerated tales to granny. In the afternoon we would be far less boisterous as my granny was home. She had a wonderful way of always keeping us out of trouble however innocent it might have seemed at the time. On her arrival home she would have a bag of goodies, these were rationed out for good behaviour and eating all of our dinner. No matter how hard we looked we could never find the treasure. When you are a child treasure is chocolate, I can remember eating a bar of chocolate and feeling a buzz, that as a young adult you can only compare to the rush you fell when you re doing something incredible dangerous. .u4178c2e1afcab19443f42c7910993874 , .u4178c2e1afcab19443f42c7910993874 .postImageUrl , .u4178c2e1afcab19443f42c7910993874 .centered-text-area { min-height: 80px; position: relative; } .u4178c2e1afcab19443f42c7910993874 , .u4178c2e1afcab19443f42c7910993874:hover , .u4178c2e1afcab19443f42c7910993874:visited , .u4178c2e1afcab19443f42c7910993874:active { border:0!important; } .u4178c2e1afcab19443f42c7910993874 .clearfix:after { content: ""; display: table; clear: both; } .u4178c2e1afcab19443f42c7910993874 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u4178c2e1afcab19443f42c7910993874:active , .u4178c2e1afcab19443f42c7910993874:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u4178c2e1afcab19443f42c7910993874 .centered-text-area { width: 100%; position: relative ; } .u4178c2e1afcab19443f42c7910993874 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u4178c2e1afcab19443f42c7910993874 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u4178c2e1afcab19443f42c7910993874 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u4178c2e1afcab19443f42c7910993874:hover .ctaButton { background-color: #34495E!important; } .u4178c2e1afcab19443f42c7910993874 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u4178c2e1afcab19443f42c7910993874 .u4178c2e1afcab19443f42c7910993874-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u4178c2e1afcab19443f42c7910993874:after { content: ""; display: block; clear: both; } READ: The Name Of War EssayOne of the things I remember the most, are the many contraptions we would strive to build. These seemed like massive undertakings for a couple of children like us and looking back they were. One day it would be a go-cart and the next a small wooden hut, the list was endless. These projects would almost always certainly end in failure for us, but to avoid having to witness our innocent faces of filled with failure granddad would undertake the challenge of building them from our simplistic plans. I will treasure these memories till the day I die. Nothing in my life will ever come close to the happiness I felt. As you get older life just deteriates into a spiral set out by todays society this only consists of stupid pettty laws and the idea you can never be good enough to meet the expectations of other people. Childhood is the only time in your life when you are not degraded and demoralised by people who think they are above you.

DC Power Supply Design
Question: Describe about the DC Power Supply Design? Answer: Introduction In this project, we have designed a power supply to convert standard UK mains AC supply to a 12V DC supply. The input voltage is 240V AC, which corresponds to a RMS value to 325V. Emitter Resistance concept of Transistor Model The transistor is used to stabilise the DC output voltage. This stabilisation is achieved by the use of an Emitter Resistance which provides the required amount of automatic biasing needed for a common emitter amplifier. This is the most used transistor configuration, which is also called common emitter transistor. Here, a large amount of current flows into the base of the transistor. The voltage divider circuit thus formed, is responsible for the stability. The emitter resistance provides more stability. This addition helps transistor to control the base bias using negative feedback. The DC negative feedback provides stable biasing. The AC negative feedback signal transconductance and voltage gain specifications. Sometimes, emitter bypass capacitor is also attached in the circuit, in parallel with emitter resistance, to break the frequency response of the circuit at a designated cut-off frequency. Here, the Emitter is not grounded, but kept at a small potential to provide the stability. VB = VE + VBE Emitter Resistance Current is given by, IE = (VB VBE)/RE By following this design concept, we make sure that the desired value to current is not exceeded in the load resistance in our circuit. Circuit Design and Simulation We have designed the desired circuit by using the components specified and following the emitter resistance concept. A small resistance of 10 Ohm has been added after the AC supply to protect our circuit from surge and our transformer. We see after simulations that diode breakdown voltages are never reached in the circuit, so diodes are protected. As we need a voltage output of about 12V DC, we use a 20:1 step down transformer, as can been seen by the inductor value of the transformer windings. After four diode drops, its gives a voltage of about 13.5V DC. The simulations under full load and no load conditions are depicted below with screenshots of the simulation on LTSpice. Fig. Circuit designed on LTSpice Calculations Calculation for the type of transformer 325V has to be brought down to 12V, with 4 diodes connected in the circuit, each with a drop of 0.7V. Keep a decent margin of about 1.5V above 12V required: 325/20 4 x 0.7 = 13.34V Calculation for Emitter Resistance Concept on Full Load RE = 500 Ohms VBE = 1V VB = 13.45V Thus, IE = 0.025A On no load condition, the current would be about 4A, or just a little less. To be 4A current exact, the load should be 3.3625 Ohms. Ripple The ripple (peak to peak) under maximum load = I/ (2fC) = 0.2V (as current decreases to a great amount in full load). Simulation Screenshots Simulation on full load: From above simulation, we see that the design requirements have been met. By this simulation, we see that about 1V difference occurs between full load and no load conditions. The voltage surge is efficiently prevented by the capacitance. Real Components for the Circuit As we have incorporated the values of all the components to be exact as the standard components available, the real components are same as the components being used in the circuit. The list of components are: 1. AC Supply SocketAvailable at the lab.2. Resistors: 10 Ohm, 10k Ohm, 5 OhmThey are standard value, can be bought from eBay at $0.5 each. Total cost: $1.53. Transformer (20:1)Can be bought online from about $35 from Amazon.com. The rating of voltage and current are as per our requirements. 4. 4 diode (1N4148)Can be bought from (https://www.mouser.in/ProductDetail/Fairchild-Semiconductor/1N4148/?qs=i4Fj9T%2FoRm8RMUhj5DeFQg%3D%3D) at $0.10 each. Total part cost: $0.505. Zener diode Can be bought from (https://www.mouser.in/ProductDetail/Micro-Commercial-Components-MCC/SMBJ5338B-TP/?qs=sGAEpiMZZMtQ8nqTKtFS%2fKiApRWFN7sOvQgw3Qc04zk%3d) at $0.806. Capacitors: 0.1uF and 5000uFCan be bought from eBay at $0.50 each. Total part cost: $17. NPN transistorCan be bought from (https://www.ebay.com/itm/100Pcs-2N3904-TO-92-NPN-General-Purpose-Transistor-/140846122431) at $1.56.8. Heat sinkIt is inbuilt for the transformer. For transistor, can be bought from (https://www.mouser.in/ProductDetail/Aavi d-Thermalloy/577404B00000G/?qs=sGAEpiMZZMttgyDkZ5WiuqcEpFN0QqoQKaPGubZmWpo%3d) at $0.82. Thus, the total cost of the project implementation is: $41.18 (approx.) Power Dissipation Power Dissipation in the transformer = 65W (maximum value) Power Dissipation in the transistor = 48W (maximum value) Thus, by using a proper heat sink, the temperature can be kept in control. The details about heat sink to be used has been attached with the list of the real components to be used. The heat sink used with the transformer is inbuilt, whereas those for the transistor should be externally mounted. Result and Conclusion The power supply has been designed successfully in LTSpice, which meet all our requirements, as seen from the simulations. The costing of the components used have been mentioned. The emitter resistance concept to stabilise the output has been implemented successfully. It gives a negative feedback to provide a stable current. An additional resistance has been added just after the voltage supply, before the transformer to prevent transformer from damage. This resistance have no negative effect on the circuit further. The real components have been identified, and as the components implemented in the circuit are available as it is in the market, no circuit changes has to be done according to it in the simulation software LTSpice. The price of real components have been mentioned (approximated value), and a total cost of the project if implemented on hardware, has been generated. References Amos S W James M R (1999).
